An email service provider implements email security to secure subscriber email accounts and data from hackers – at rest and in transit.

Techopedia Explains Email Security

Email security is a broad term that encompasses multiple techniques used to secure an email service. From an individual/end user standpoint, proactive email security measures include:

  • Strong passwords
  • Password rotations
  • Spam filters
  • Desktop-based anti-virus/anti-spam applications

Similarly, a service provider ensures email security by using strong password and access control mechanisms on an email server; encrypting and digitally signing email messages when in the inbox or in transit to or from a subscriber email address. It also implements firewall and software-based spam filtering applications to restrict unsolicited, untrustworthy and malicious email messages from delivery to a user’s inbox.
